Dynamics AX 2009 VPC Refresh 3.5 Workflow

Hi

Is there any problem with Dynamics AX 2009 Refresh 3.5 Purchase Requisition Workflow? I am using VPC with out any changes in workflow settings. When I create purchase requisition and submit it shows pending status and no notification is received by assignee.

To check status when I view workflow history the “assigned to” grid was empty, while in workflow configuration it is assigned to Purch complete role (pre set in Refresh 3.5).

Is there anything to be done in Refresh 3.5 to run workflows?

Regards
